CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a Divisional of U.S. application Ser. No.15/042,984, filed Feb. 12, 2016, which claims priority under 35 U.S.C. §119 and 35 U.S.C. § 365 to Korean Patent Application No.10-2015-0022169, filed in Korea on Feb. 13, 2015, whose entiredisclosures are hereby incorporated by reference.

BACKGROUND 1. Field

The present disclosure relates to a cooking apparatus.

2. Background

A cooking apparatus may be an apparatus which cooks food using heat froma heating source. As an example of the cooking apparatus, an oven rangemay include an oven chamber in which the food is cooked, and a burnerwhich may cook the food in the oven chamber by burning a gas. An ovenrange is disclosed in Korean Patent Publication No. 10-2010-0013997(published on Feb. 10, 2010) whose entire disclosure is herebyincorporated by reference. In the oven range, a burner chamber may beprovided under a bottom surface forming an oven chamber, and a lowerburner for convection-heating food in the oven chamber may be installedat the burner chamber.

To transfer air heated by the lower burner from the burner chamber tothe oven chamber, the oven chamber and the burner chamber are incommunication with each other. However, since the burner chamber isprovided under the oven chamber, a part of a bottom surface of the ovenchamber should be opened. When a part of the bottom surface of the ovenchamber is opened, food leftovers or the like may be introduced into theburner chamber through an opening between the oven chamber and theburner chamber, while the food is put in or taken out of the ovenchamber. Therefore, a product may be contaminated by the food leftoversor the like.

Since a part of the bottom surface of the oven chamber is opened, theremay also be a problem in that it is not easy to clean the oven chamberdue to the opening of the bottom surface. A cavity capacity may be alsoreduced by a burner installation space since the lower burner isinstalled under the oven chamber. Due to the lower burner being locatedunder the oven chamber, it may be also difficult to take the lowerburner out of a cooking chamber unless the cooking apparatus isdisassembled.

The second cover 160 mayfurther include a burner through-hole 167 through which the burner 110may pass.

Referring to FIGS. 4 and 7, the burner 110 according to the embodimentmay include a burner tube 111 of which both ends are spaced apart fromeach other. In the embodiment, the burner tube 111 may be formed in anon-annular shape. At least a part of the burner tube 111 may beinformed in a “U” shape, but is not limited thereto.

A supply part 118 through which the gas and the air are supplied may beprovided at a first end 112 of the burner tube 111, and a second end 113of the burner tube 111 may be blocked. The supply part 118 may beconnected to the nozzle holder 220. The supply part 118 may extend to beinclined from the first end 112 of the burner tube 111. Therefore, aflow direction of the gas and the air supplied through the supply part118 may be changed at the first end 112, and then the gas and the airmay flow along the burner tube 111 toward the second end 113. The gasand the air supplied through the supply part 118 may flow in the burnertube 111 in only one direction.

The entire burner tube 111 may be formed in a curved shape, or one ormore of the first end 112 and the second end 113 may be formed in alinear shape, and the other portions thereof may be formed in the curvedshape. The burner tube 111 may include an inner circumferential surface111 a and an outer circumferential surface 111 b.

A plurality of gas outlet holes 116 may be provided at the outercircumferential surface 111 b of the burner tube 111. The plurality ofgas outlet holes 116 may be arranged to be spaced apart at regularintervals from each other in an extension direction of the burner tube111. The burner 110 may be fastened to the burner cover 130, and thus aposition thereof may be fixed.

Referring to FIGS. 4, 8 and 9, the fan cover 180 may divide an internalspace of the frame 21 into the cooking chamber 22 and an air flowchamber 22 a partitioned from the cooking chamber 22. Therefore, the fancover 180 may be referred to as a partition plate. The burner cover 130may form the combustion chamber C in the air flow chamber 22 a. A spacein the air flow chamber 22 a in which the air in the cooking chamberflows may be a space between the burner cover 130 and the fan cover 180.

The fan cover 180, the first cover 140, the second cover 160 and therear wall 35 of the frame 21 may be fastened with a single fasteningmember (or fastener) 230, but the embodiment is not limited thereto. Thefastening member 230 may pass, in turn, through the fastening hole 187of the fan cover 180, the first fastening hole 154 of the first cover140 and the second fastening hole 168 of the second cover 160, and thenmay be fastened to the rear wall 35 of the frame 21.

While the burner assembly 23 is fastened to the rear wall 35 of theframe 21, at least a part of a front surface of the burner cover 130 maybe spaced apart from at least a part of a rear surface of the fan cover180. The first cover 140 may be spaced apart from the fan cover 180.

The fan 200 may be located between the first cover 140 and the fan cover180. Therefore, the burner 110 may be located closer to the rear wall 35of the frame 21 than the fan 200. The fan 200 may be located between onewall of the frame 21 at which the air introduction hole 354 is formedand the air inlet port 185. While the fan 200 is located at the fanaccommodation portion 143 of the first cover 140, the fan 200 may bespaced apart from the fan cover 180.

The burner 110 may be located outside the air introduction guide 164while being fixed to the burner cover 130. At least a part of the burner110 may be positioned to cover an outside of the air introduction guide164 while being spaced apart from the air introduction guide 164.

A distance from a center (or the shaft of the fan motor) of the fan 200to the air through-holes 146, 147 and 148 may be formed longer than adistance from the center (or the shaft of the fan motor) of the fan 200to the outer circumferential surface of the burner 110 so that the airin the air flow chamber 22 a may be rapidly heated by the flamegenerated from the gas outlet holes 116. Therefore, the flame generatedfrom the burner 110 may extend toward the air through-holes 146, 147 and148.

When the operation of the burner assembly 23 is started, gas may beinjected from the nozzle holder 220 to the supply part 118 of the burner110. Air (A1) (air outside the frame) around the supply part 118 maythen be supplied to the supply part 118 together with the gas. At thistime, since a low pressure is formed around the gas supplied to thesupply part 18, the air (A1) around the supply part 118 may be naturallysupplied to the supply part 118 due to a pressure difference (in anatural ventilation method).

When the air is supplied to the supply part 118 in the naturalventilation method, the air necessary to burn the gas may not besufficiently supplied to the supply part 118. In this case, an imperfectcombustion of a mixed gas in which the gas and the air are mixed mayoccur in the burner 110, and thus there may be a problem that a carbonmonoxide generation rate due to the imperfect combustion is increased.

While the fan 200 is rotated, additional air A2 for combustion of themixed gas in the burner 110 may be introduced into the combustionchamber C through the air introduction hole 354 of the frame 21 and theair introduction openings 166 of the burner cover 130. Since theplurality of air introduction openings 166 are arranged at thecircumference of the air introduction guide 164, the air may be evenlysupplied to the burner 110. Since the additional air A2 is smoothlysupplied to the combustion chamber C, the imperfect combustion of themixed gas in the burner 110 may be minimized, and thus the carbonmonoxide generation rate may be minimized.

When the fan 200 is rotated, the air in the cooking chamber 22 may beintroduced into the air flow chamber 22 a through the air inlet port 185of the fan cover 180. At this time, air A3 introduced into the air flowchamber 22 a may flow toward the air through-holes 146, 147 and 148. Theair A3 flowed toward the air through-holes 146, 147 and 148 may beheated by heat of the flame of the burner 110 discharged through the airthrough-holes 146, 147 and 148.

The additional air A2 introduced into the combustion chamber C may beused for the combustion in the burner 110, pass through the airthrough-holes 146, 147 and 148, and may then be introduced into the airflow chamber 22 a. The additional air A2 introduced from the combustionchamber C into the air flow chamber 22 a may be discharged again to thecooking chamber 22 through the air outlet port 186 of the fan cover 180together with the air A3 introduced from the cooking chamber 22 into theair flow chamber 22 a.

Since the plurality of air through-holes 146, 147 and 148 may bearranged along the circumference of the fan accommodation portion 143,the heat of the burner and the heated air may be evenly introduced intothe entire air flow chamber 22 a. Accordingly, the air A3 in the cookingchamber introduced into the air flow chamber 22 a may be rapidly heated.Since the fan 200 may be located at the fan accommodation portion 143 ofthe burner cover 130 in the air flow chamber 22 a, a forward andbackward width of the burner assembly 23 may be prevented by the fan 200from being increased, and thus a volume of the cooking chamber 22 may beincreased.
